C for Experienced Programmers

Displaying courses for Great Britain [Change]


C is one of the most widely-used languages for systems software and workstation application programming, largely due to its power and flexibility. This course will provide you a highly effective, structured approach to learning ASCI Standard C revision C90 for experienced programmers who have had some exposure to similar languages such as Java or C#.

Programming skills will be enhanced as delegates will be able to use the powerful features of C to best effect building on the skill gathered from their previous experience in similar high level languages. The QA's C programming Course for Experienced Programmers is outstanding because of its emphasis on writing style, pitfalls to avoid and techniques to use that make the code clear, concise and maintainable. It is designed to accelerate through the foundations of C programming as appropriate to the skill level.

In addition to the lecture material there are graded practical sessions that cover each of the major areas of C. There are also optional exercises for further study after the course. Delegates may take away worked solutions, together with some small sample demonstration programs.


At the end of this course you will be able to:

  • Use all the major elements of the C language
  • Write programs using the strengths of the C language, for example aggregate types, pointers and dynamic data structures
  • Write and use the data structuring features of the language, which can result in better program design and maintenance
  • Work with the C run-time library: a major source of programmer productivity and portability
  • Dealing with errors, both by spotting and remedying common programming errors and using C's error handling facilities
  • Write in a good C programming style without compromising efficiency and integrity


Delegates must have professional programming skills and a good working knowledge of a C-like language together with the usual skills in a block-structured language, such as Basic/Visual Basic, Pascal/Modula2, Fortran, Algol or PL/1, and be familiar with a programming environment.
